BOX-BLANK MACHINE.

. Specification' of Letters Patent.

Application led October 4, 1909. Serial No. 520,888.

To all whom it may concern Be it known that I, JASON H. GREEN- sTREET, acitizen of the United-States, residing at Indianapolis, in the county of-Marion and State of Indiana, have invented certain new and usefulImprovements in Box-Blank Machines, of which the following is aspecification.

The obje-ct of my present invention is `to produce an efficient machinefor forming boxes by means of wiring and stapling the sides, tops andbottoms to the ends, especially that class of boxes which are made ofthin stock with the ends paneled. In many respects' this machine issimilar to that shown and described in Letters'Patent No. 652,357 issuedto Jason H. Greenstreet, June 26, 1900, especially in .the wire-cuttingand staple-driving mechanism, which are practically identical with thoseshown in said patent. The .subject of the present invention is'moreyespecially the means of tting and manipulating' the stock of which theboxes are formed, as will be hereinafter more particularly described andclaimed.

Referring to the accompanying drawings,

Vwhich are made a part hereof and on which similar reference charactersindicate similar parts, Figure 1 is a top or plan view of a machineembodying my present invention; Fig. 2 a side elevation thereof; Fig. 3a vertical sectional view on an enlarged scale as seen when looking inthe direction indicated by the arrows from the dotted line 3 3 in Fig.4; Fig. 4 a view'as seen when looking downwardly from the broken line 44 in Fig. 3, showing `the central portion of the .machine table and itsstock feeding mechanism in plan; Fig. 5 a transverse vertical sectionalView as seen when looking in the direction indicated by the arrows from'the dotted line 5 5 in Fig. 3; Fig. 6 a detail view on a considerablyenlarged scale as seen when looking in the direction indicated by thearrows from the broken line,6 6 in Fig. 4, illustrating one of thedriving instrumentalities more clearly; Fig. 7 a detail viewillustrating that portion of the machine where the staples are formed,driven and clenched;

Fig. 8.a detail `plan view of the train of shafts, gears and beltsforming thedriving mechanism as. seen when .looking down-` wardly fromthe brokenline 8 8 in Fig. 3; Fig. 9 a transverse vertical sectionalview as seen 14 and 15 perspective views of different forms ofseparators or spacing devices by Patented J an. 14, 1919.

means of which the cleats are held to proper relation while passingthrough the machine; Fig. 16 a perspective view ofa row of such cleatswith said spacing devices between them, and Fig. 1,7 a perspective viewof one corner of the box structure which the form of machine illustratedis especially designed to produce.

The box structure in question is composed of cleats forming the edges ofthe ends, and suitable siding secured to said cleats. Each end has fourcleats corresponding in length to the widths of the sides and bottom andtop of the box. In Fig. 16 I have illustrated a set of these cleats in abox'which is comparative'ly narrow in one of its dimensions, so that twoof thecleats 21 and 23 are of considerably less length than the othertwo, 22 and 24. In Fig. 17 two cleats 21 and 22 are shown in theirfassembled condition,-

that is at right angles with each other5 and with ythe tongue-and-grooveformation interlocked. Fragments of siding 25 are lalsov shown assecured to said cleats in the manner in which that work is performed bymy improved machine by means of the wires 26 and staples 27 l I ncompleting the box there are of course additional pieces of siding toform the panels completing the ends; but,

as this is not a part of the work performed by my improved machine,.itis not shown and will not be further described, it being rmerely beingeither of the form of block 31 shown in Fig. 13; of the form of block 32shown ,inv Fig. 14, or of the form of block 33 shown in Fig. 15) isinterposed between the ends of adjacent cleats, so that the same areheld in proper relation, and are permitted to turn and interlock atl theproper time as shown in Fig. 17. Between eachset of four cleats a longerdistance block is inserted, so thatthe cleat 21 of the neXt set is heldoff a suflicientdistance to permit the wires (one of these wires w isshown in Fig. 2) to be cut and leave an en d which can be twistedtogether with, or' overlap, the `preceding corresponding end, when theparts are brought together. This is illustrated at the left hand end ofFig. 16, where a fragment of the cleat 21 of a second set is shownspaced ofi' to appropriate distance by the longer distance block. Theadditional length of distance block is indicated by the dotted lines.

in Fig. 13.

The complete machine is illustrated on a small scale in Figs. 1 and 2.The staple forming and driving mechanism is carried by a central frame41, but is not illustrated in much detail, and will not be more thanincidentally described herein, for the reason that it is substantiallyidentical with that forming the subject-matter of the Greenstreet PatentNo. 652,357 above referred to, although somewhat improved in form. EX-tending out in each direction from this central frame are suitable framesides 42, 43,

and 45. Upon cross braces 46, extendingl between the sides 42 and 43,are guideways which receive the cleats which have been referred to, andalong which said cleats and 4the boX siding ltravel to the point wherethe stapling operation takes place. These guideways are each composed ofa' base plate 51 and two angle irons 52 and 53 secured thereon, one ofsaid angle irons being of less height than the thickness of the cleats,while the other is of greater height, as is best shown in Figs, 6 and11. The two angle irons 52 and 53 are adjustable toward vand from eachother in`order to accommodate cleats of various thicknesses, and theguideways as a whole are adjustable toward and from each other on thesupporting frame bars 46 in order to accommodate box structures ofvarious sizes.' As will be noticed, especially in Figs. 6 and 11, thesides 53 of the guideways form guides for the ends'of the siding 25, aswell as for the cleats 21, etc. A thin bar 51 is shown in the bottom ofthe guideway channel 'in Fig. 6. This is used when cleats of smallerdimensions than standard are being used, and is a mere filler or falsebottom. As also best shown in Figs. 1, 2 and 11, overhanging arms 54secured4 to the guideways carry overhead guiding bars .55y which preventthe siding downwardly onrthe.A material with which itA engages, and theresult is that the cleats 21 are drawn down closely onto the bottoms ofthe guides. The disk shafts are provided respectively' with sprocketgear wheels 63y and. 64, nwhich are connected by' sprocket chain 65,which driveone from the other. Upon the lower end of one of saidshafts-is a pinion 66, and this engages with a bevel gea!` Said shaft 68has on its outer end a friction clutch, one member 69 of whichA isrigidly fixed thereto, and the other member 70 of which is in the formof a loose pulley. lThe pulley 70 is driven by a belt 71 (see Fig. 2)running from the corresponding pulley 72 on'shaft 73, which said shaft73 is directly below the shaft 68. Shaft 73 is driven through a sprocketbelt 74 from main shaft 75, and the latter is driven in anysuitablemanner, as by belt7 6 running to pulley 77 from any suitable source ofpower (not shown). The feeding disks 61 and 62, being in engagement withthe cleats which Aare being fed forward, drive said cleats and thesiding up to the position for the stapling operation, and hold them andthe interposed spacing devices closely against each other, end to end.The forward movement of the material must however be intermittent (aswill be presently explained) -to enable the stapling to be performed,and the friction clutch device (consisting of'parts 69 and 70) permitsof a lslippage at any time when the stopping of the movement of thematerial renders it necessary.

The nal means for' moving the material forward consists of a pair of-spurred chains 81 and 82 which tra-vel along the sides of the guidewaysbeneath the jstapling mechanism, and anti-friction rollers 83 mountedopposite said spurred chains. Said chains are carried by sprocket wheels80 on verti-A which is adjustably connected to a slottedl arm 88 uponwhich is carried a pawl 89 wheel 67 on one of the machine shafts 68. f

. stood.

It frequently happens, however, on account of the varying widths of thesiding which is to be fastened to the cleats, that the otherwisedesirable regular movement should be varied from, in order that thestaples or fastening devices may be driven into the siding forming thewalls of the box at 'suitable distances from the edges thereof.

To enable this to be properly done I providea hand wheel 91 having ashaft 92 mounted in bearings at a suitable and convenient point on themachine, and one of the operatives constantly has a hand upon thiswheel. Upon the inner end of this shaft 92 is mounted a sprocket wheel93 from which a chain belt 911 runs to a corresponding sprocket wheel 95on shaft 86. The operative, 'by turning hand wheel 91, either when thefeeding devices are at rest, or when in operation at a somewhat greaterspeed than the ordinary motion of shaft 86, is capable of varying themovement 'of these final feeding devices, and thus bring the materialtoexactly the point below the stapling mechanism which is necessary tocause the staples to enter the wood at exactly the required point. Thismovement is commonly made just at the time the feeding devices havestopped their normal movement, and just before the stapling mechanismoperates, whenever it is seen that the strip of siding to be stapledonto the cleats has not moved to just the point which is best.

As 1 have heretofore stated,` one of the guideways and the accompanyingfeeding mechanism is adjustable toward and from the other, toaccommodate box stock of varying lengths. As best shown in Figs. 4, 9and 10, 1 have provided a hand wheel 101 having a screw 102 whichengages with a nut n fixedly connected to a portion of one of theguideway structures. There is also upon this screw or screw shaft asprocket wheel 103, and a chain belt 104 leading thence to acorresponding sprocket wheel on a shaft. 105 (see especially F ig. 1)near the other end of the machine, and which engages with acorresponding nut Iixedly secured to the guideway structure at thatpoint. As will be readily seen, turning the hand wheel 101 will move oneentire guideway structure and the portion of the feeding mechanismcarried' thereby toward or from the other guidewav structure, exceptthat one of the top guiding bars 55 is secured at its inner end to across bar 55 by means of a set screw (see especially Figs. l` and 12)and in order to move said bar 55 said set screw must be loosened and themovement performed by hand.

Asis best shown in Figs. 1 and 2 I provide at the end of themachine fromwhich the box material after it has been treated emerges, a hopper 111,from which an inoline-d trough 112 leads back to the opposite end of themachine. A carrier 113 runs in this trough. The lower oropen end of thehopper is positioned immediately above the trough and Carrier, so thatthe contents will discharge onto said carrier. This hopper is designedto receive the distance blocks (31, 32 or 33 according to which style isused) after they have performed their work; and, by means of saidcarrier, said distance blocks are continually carried back bythe pointof use, where an operative may conveniently get them for repeated use.
